I currently run a Hamilton ER-60 with a new XE validator installed. I should have made it a Mars. My only HUGE complaint with the Hamilton has been the stacker...and yes, I purchased a new one...jams on a busy day hurt...I called Hamilton...removed the teeth...still had the problem. So, I run it without a stacker. I think it's funny the company that makes the stacker actually says it's normal to have to run it minus a part it comes equipped with...and for that reason...I'm evaluating other options on my second changer...yes, it will have a mars, but what should it be?...American or Rowe? My only experience with them has been as a customer in my days before I owned a car wash. I'm going to leave my Hamilton in place, but install an additional changer on the opposite side of my car wash (vending area)...which is where my changer should be anyway...not my design though. I'm going to start tokens in the ER-60 instead of the quarters it currently dispenses...my reason being I would like to push things more towards tokens without doing it all at once. I've been to my competition wash...he runs a new dual American changer...and it sucks bills so fast it makes my XE look pathetic. I have to actually help some customers with the XE validator...and yes I keep it clean. It just doesn't love ALL money as much as some of the other machines I've been around...and no, I didn't try to string my competition's changer. lol I just want to keep everyone happy...I currently have slugbusters accepting tokens/quarters in my bays as well as my vacs...vending machines are quarters only...which I'm wondering what my remedy for that may be...although the quarter dispensing machine will be beside my vending machines. I know this is a ramble...but I'm thinking of picking up a used Rowe BC200 to team up with my ER60...although with the mars conversion kit being so costly for a Rowe...it makes a cheap new American with a mars validator sound like a viable option.
